"Sprint wants you to believe that two screens are better than one. Its new Android-powered smartphone, the Echo, will feature two touchscreen surfaces in a hinged design. Made by Japanese electronics manufacturer Kyocera, the phone’s dual 3.5-inch WVGA screens can be operated independent of one another or combine in 'tablet mode' to add up to a single 4.7-inch integrated display (albeit one with a hinge in the middle)."

Wouldn't that guzzle up your battery, or are they planning to put a high-capacity battery in it? One touch screen on most phones guzzles enough power right now, I can't imagine how fast two of them would drain a typical 1900 or 2100 mA phone battery on top of Android's generally inefficient process management.

Also still unknown is the phone’s battery life, although here’s a hint: Sprint is bundling it with a spare 1,370 mAh battery and a “low-profile” charging cradle that can also act as an external battery pack. In other words, you’re probably going to need that extra juice.
